Quick TakeThe Sinn 456 St GG I is where technical precision meets understated refinement. Its 28mm polished stainless steel case, beautifully offset by an 18-carat yellow gold decorative ring, creates a truly distinct visual. It's not just a pretty face – the robust construction and 20 bar water resistance rating confirm its capabilities. The subtly shimmering, Black electroplated dial and hand-applied indices speak to the detailed craftsmanship. The anti-reflective sapphire crystal, protects this artwork, all while on your wrist. Flip it over, and the exhibition case back reveals the intricate dance of the SW 100 automatic movement. The gold-plated elements integrated into the stainless-steel bracelet continue the two-tone theme of this stunning watch. The addition of luminescent material on the hands and indices means that the dial still pops, even in darker lighting. Every single technical detail is engineered perfectly to be seen, while the watch is functional. It will not let you down, where ever, when ever.

DescriptionThe Sinn 456 St GG I, reference 456.020, is a meticulously engineered timepiece built for both elegance and resilience. Its case, with a diameter of 28 mm, is constructed from polished stainless steel, offering a robust foundation. A defining feature is the decorative ring encircling the dial; this component is crafted from polished 18-carat yellow gold, providing a luxurious contrast. The watch's total case thickness measures 9 mm, contributing to a slender profile on the wrist. The band lug width is specified at 14 mm, designed to accommodate the included polished solid stainless steel bracelet, that has gold-plated elements. The total weight of just the head, excluding strap and bracelet is 32 grams.

Protecting the dial is a sapphire crystal glass, treated with an anti-reflective coating on both its interior and exterior surfaces to ensure optimal legibility under various lighting conditions. The case back also uses a sapphire crystal, anti-reflective on the interior, providing a view of the mechanical movement within. This case back is screw-fastened, contributing to the watch's overall water resistance. The 456.020 meets the technical requirements for water resistance as defined by DIN 8310 standards and is pressure-resistant up to 20 bar. The movement powering the Sinn 456 St GG I is the SW 100, a self-winding mechanism. This caliber incorporates 26 bearing jewels. Its balance wheel oscillates at a frequency of 28,800 semi-oscillations per hour (4 Hz). The movement includes a seconds stop function (also know as hacking) enabling precise time setting. The movement its self has anti-magnetic as per DIN 8309. The dial itself is Black electroplated, providing a stark backdrop for the meticulously hand-applied appliqués. Both the appliqués, along with the hour and minute hands, are coated with a luminescent material.
